Two stories about genetics produced by students at the University of Otago's Department of Science Communication. Amanda Konyn investigates whether gene editing has a role in future pest control, while Richard Marks explores why the "eat less, move more" approach to weight loss isn't really working.
An eye in the sky to detect methane emissions
An eye in the sky to detect methane emissions
MethaneSAT is the first New Zealand government funded space mission. A joint project between the United States' Environmental Defense Fund and New Zealand, the project will see a methane sensing satellite launched into orbit. Science journalist Peter Griffin finds out why and how.
Conservation successes in the Cook Islands
Conservation successes in the Cook Islands
The kākerōri or Rarotongan flycatcher is a South Pacific conservation success story. Once reduced to just 29 birds, it has been rescued from the brink of extinction by a rat control programme managed by the land-owners of the Takitumu Conservation Area in the Cook Islands. Alison Ballance visits to find out more.
Planning for Aotearoa's genomic medicine future
Planning for Aotearoa's genomic medicine future
If the future of healthcare is personalised genomics, how can we ensure that it is used to lessen inequities, rather than strengthen them? This week, Our Changing World speaks to two of the co-leaders of the Rakieora programme - a pilot to develop a New Zealand-specific national database for genomic research.
Sunfish secrets
Sunshine science: the power and peril of the sun’s rays
Sunshine science: the power and peril of the sun’s rays
Summer is on its way, and this week we're exploring both the power and the peril of the sun. First, we visit the Ultrafast Laser Lab to learn about efforts to create better solar panels. Then, we hear about one professor's quest to teach kids about sun safety using an ultraviolet dosimeter you can wear on your wrist like a watch.

Space sounds and jungle noises The otherworldly song of Weddell
Space sounds and jungle noises The otherworldly song of Weddell
Weddell seals have returned to breed near Scott Base in Antarctica after a decades-long absence. On land, they're blubbery lumps. But underwater, they're graceful dancers and ethereal singers. A team of scientists is finding out more about the under-ice lives and habits of Weddell seals. Alison Ballance joins them in this episode from the award-winning series Voices from Antarctica.

The prickly prize of ongaonga
The prickly prize of ongaonga
It's spectacularly spiky and delivers a painful or even deadly sting. Why are a team of conservationists growing and planting up Orokonui Ecosanctuary near Dunedin with more and more native tree nettle, ongaonga? It's all because of a pretty little pollinator called the kahukura, or red admiral butterfly, and its prickly preferences. Claire Concannon visits Orokonui to learn more about the ongaonga-kahukura relationship, as well as new research investigating whether these native butterflies are the victims of a sneaky ecological 'trap'.
A send-off for SOFIA, the flying observatory
A send-off for SOFIA, the flying observatory
We're saying farewell to the Stratospheric Observatory for Infrared Astronomy (aka SOFIA) this month. The mission, which was partially based in Christchurch, wraps up after a decade of observing comets, stars, planets, and the moon. In July 2017, Alison Ballance boarded the Boeing 747 with a flying telescope for one of its research flights.
